Structural magnetic resonance imaging include lineal mesure, volume measure and volume rendered. They can detect the abnormal brain structure, especially the change of mesial temporal lobe in early onset of Alzheimer s disease. Recent studies more focused on functional imaging which can find the functional changes in brain. Prior to structural changes, functional changes happen, so it can reflect the sutile pathological process in Alzheimer s disease.

Meanwhile, the three-dimensional mechanical characteristics of calcium thenardite salt rock take great changes after a period of solution pervasion actions. The compression strength of calcium thenardite rock salt changes from 46.53MPa to 11.42MPa after 49h solution pervasion with 2.0MPa confining pressure. Accordingly, the elastic modulus changes from 43.700MPa to 0.834MPa.

Reactive oxygen species causing DNA oxidative damage comes from two kinds of ways:one is from cellular normal physiological metabolism;the other is from outer environment.Redox-sensitive green fluorescent protein was expressed in Saccharomyces cerevisiae.Recombinant cells were evaluated in monitoring the changes in the redox state of living cells when challenged with toxicologically relevant metal ions NaAsO_2 or Pb(NO_3)_2 by measuring emission intensity at 510 nm with a Hitachi F6500 fluorescence spectrophotometer,roGFP expressed in yeast responded not only to typical membrane-permeant oxidants H_2O_2 and reductants DTT,but also to toxicological metal ion-induced intracellular redox changes in a dose-dependent manner.Moreover,exposure of yeast cells to NaAsO_2 or Pb(NO_3)_2 at concentrations that induced redox changes reported by roGFP caused up to 2～3 fold increases in DNA mutation frequency.This mutagenic effect was largely caused by oxidative stress since blocking the production of hydryl radicals with thiourea significantly reduced the mutation rate as well as delayed the cell death.

本文将对氧化还原状态变化敏感的绿色荧光蛋白roGFP1-R12，在酵母细胞中实现了多拷贝强表达；荧光扫描经强氧化剂H_2O_2和还原剂DTT以及环境中重金属NaAsO_2或Pb(NO_3)_2处理后的酵母细胞悬液，测定510 nm处的荧光发射强度结果显示，表达的绿色荧光蛋白对氧化还原水平敏感，且在510 nm处的荧光强度与一定的重金属浓度呈正相关，即roGFP1-R12在510nm处的荧光发射值随重金属浓度的增高而增强，从而说明重金属对细胞的毒性在一定程度上很可能是通过破坏细胞内的氧化还原平衡发生作用；同时通过该绿色荧光蛋白对胞内氧化还原状态变化的响应情况可以来实时检测环境中的重金属；遗传学的点突变频率及致死率实验数据表明，重金属能导致菌体的点突变频率和致死率升高，且活性氧的清除剂巯基脲能明显降低这种点突变和致死率，说明由重金属引发的这种点突变和致死效应在很大程度上是依赖于重金属对细胞诱导产生的氧化胁迫。

Schizophrenic CSF can result in significant pathologically ultrastructural changes of neurons and cerebral capillaries of macaque' brain. CSF of patients with brain atrophy can produce more serious pathological changes than CSF of patients without that. Abnormal microvessel milieus may probably contribute the neuron pathological changes and play an important role in biological mechanism of schizophrenia.

The results presented in this paper show that aggregating trades with positive and negative price changes obfuscates analysis of the role of different sized trades on cumulative price changes. By disaggregating up-tick and down-tick trades, we find that small trades make a greater contribution to cumulative price changes than any other trade category.

然而，先前的研究都是总合正和负的股价波动，这个方式对於隐藏性交易的影响难以理解，所以本研究分别将股价变动分为正和负两种，其实证结果发现，不论是up-tick或者是down-tick均是小额交易所造成的累计股价波动相对来的大。
